UNITED sTAr s PATENT OFFICE ALBERT PERCI FULL; OF MERCER,

AUTOMOBILEJACK.

Application filed March 21. 1919.

This invention relates to an automobile jacltor an automobile lifter, and has for its object the construction of a comparatively simple and ellicient jack or lifter that can be quickly operated for lifting an autmnobilo or motor vehicle so that the tires will be caused to clear the floor of a garage or shed and thereby remove the weight of the vc hicle-oti'.tlie tires, increasing thelife of said tires. v i

'll'ith this and other objects in View, my invention comprises certain novel construo tions. combinations, and arrangements of parts as \vill'behereinafter specifically described. illustrated in. the accompanying drawings. and more particularly pointer out in the appended claim.

In the drawings,

Figure l is a view in side elevation of a mechanism constructed in accordance with the present invention, showing the men-luv nism in an inactive or unset position. while Fig. .2 is a similar view showing the mechanism in an active or set position for holdingrthe tires oil the floor or ground.

Fig. 3 is a sectional View taken 'on line 33, Fig. 2.

Fig. 4 is a perspective-view of the base structure and the lifting; device of the mechanisnr Fig. 5 is a plan view of one of the link beams.

Referring to the drawings by numerals. I

' designates the floor or ground of a shed or garage, and resting upon the floor is the base structurol of my mechanism; the lifting device, (Fig. 4) of the mechanism works between the base or primary structure and the upper or auxiliary structure- 4.

The base structure comprises parallel beams 5 which are secured together at one ond by inset. transverse plate or board 6. and the opposite ends of the beams are held together by a stationary U-shaped bracket 7; bracket 7 being boltrd to the beams- 5 at 8.

"shapedbracketst l; the brackets 5) extending through thebeams 3 and having their upper ends 10 (Fig. 3) projecting inwardly, upon which are mounted the parallel beams 11 of the lifting device. 011 the, up )(21' ends 10 of the brackets '9, andengaging t hc outer faces:

of the. beams 11, are rollers 1'2. The rollers 12 are provided for irceiviug the beams 13 of the upper or auxiliary structure or automobile-engaging frame Secured to the in nor faces otthe beams ].,1 near one end, are bearing blocks H, and arlmtting against the inner ends of these blocks are the inner ends of the link beams; each link beam comprises an inner end 15, an outer end if and an intermediate, central portion 17, The ends 1:") and 16 are parallcb whereas the central. portion-17 is constructed at an angle to the ends 15 so that the inner ends 15 may be so- -cured at 18 against the, inner faces of the beams 11, and positioned between the outer endslG-js lever 19. Lover 19 has a broad base 20 provided with a flat on straight lower end that engages snugly the upper face of the transverse, plate 6 when the mechanism is in a set position, The ends 16 of the link beams are connected at 2:3 to the broad base 20 of the lever, and the lever also connected at 23 to the parallel-stag porting blocks 24 secured to the central por tion of the transverse plate 6. A sto -picre or plate is secured to the upper edge s m; faces of beams 11 and the inner edge m" this stop-piece 25 engages the stoppiece 28 aecured to the under face of the beams 13 of the auxiliary or automobilea-engaging frame (Fig. 2).

The auxiliary or autonmbilecngaging frame comprises said parallel beams 13 which are plvotally connected at 27 to short link beams 28, which link beams 28 are pivotally connected at 29 to the upper ends of the U-shaped stationary bracket 7. A transverse plate or piece 30 is secured to the beams 5 near bracket 7, and an angularly disposed brace 31 is secured at one end to the bracket 7 and at its other end to this plate or piece 30, for the purpose of cliiciently bracing the bracket 7. As mentioned hcreinbefore, the beams 13 are adapted to engage the rollers 12 and travel slightly thereon; to prevent displacement of the auxiliary frame off these rollers, I provide guiding plates or pieces 32 on the sides of the beams 13, at their outer ends, that projcct a considerable distance below 'ibr beams and overlap the sides of the rollers 12 carried by the outer swinging bracket 9 (Figs. 1, 2, and 3). These guiding pieces or plates 32 prevent any dis lacementof the auxiliary frame, insuring 0 positive action when the lever ls swung to set the frame, or in other words, lifting the automobile off the floor 1 as shown in dotted line'sin' Fig. 2.

The 'ack can be placed uic ly under an automo ile, or an autcmo ile can be run over the jack fromeither end thereof, and

then the lever swung to raise the automobile at the will of the 0 erator. I

If an automobile as a truss rod as a art of its running gear, then -I prefer to p ace angle supports 33 under the axle 34 to suport the "weight at that end of the automoile without causing the weight to rest upon the r'od 35.v Each of the angle supports is laid upon the top of a beam 13, and comrises a substantially-horizontal central integral at one end with the rightang ed extension 36 and at the other end with a downwardly-inclined portion 37.

\Vhen the lever is swung to. its set position, by reason of its broad, straight edge 21-, it will be practical] impossibleto accidentally tri orswing tiie'lever, thereby securely ho ding the entire mechanism in its set or raised position (Fig.2).

The link beams 28 are braced by a trans-.

versestripor plate 38, and the beams 13 are braced by a transverse strip or plate 39 in addition to the stoplate or piece 26.

I wish it to be un derstood that I reserve the right to make certain minor alterations ,or changes to my mechanism as shall appear to one s illed in the art to which this invention relates, which minor changes or alterations shall fairly fall within the scope of the appended claim.

' \Vhat I claim is:

In a mechanism of the class described, the combination of a base frame provided with an inset transverse piece at one end, a lever provided with a broad, straight base pivotally mounted upon said transverse piece, a U-sha ed bracket secured upon the opposite end 0 said frame, an auxiliary frame, links pivotally connected at their inner ends to the inner end of said auxiliar frame and having their outer ends pivotaily connected to the upper ends of the U-shaped bracket, a swinglng and vertically-movable lifting device between said base frame and said auxiliary frame, and single link beams having their inner ends pivotally connected to the lifting device, and their outer ends brought close together and pivotally connected to opposite sides of said lever.

In testimony whereof I hereunto aiiix my signature.

ALBERT PERCIFULL.
